Description

  The present invention relates to a desktop stand device.

A magnifying glass, lighting equipment, or the like may be required to perform fine operations such as assembling and adjusting the sewing machine or correcting threading and thread jamming during sewing. In these cases, since it is difficult or impossible to work with a magnifying glass or a lighting fixture with one hand, various stand devices that can support them at a predetermined height have been proposed.
In this type of stand device, in order to be able to freely set the support height and support angle of the magnifying glass and the luminaire, a bellows tube is adopted for the portion to be the support column (for example, Patent Document 1) For example, a structure combining a telescopic tube and a universal joint has been adopted (for example, see Patent Document 2).

Utility Model Registration No. 3147909 JP 2002-148527 A

Conventionally known various stand devices have the disadvantage that the assembly of the device as a whole becomes troublesome and costly, especially because a complicated structure is employed in the portion serving as the support column. In addition, since it tends to be heavy in weight, handling is inconvenient. Therefore, these have become a bottleneck and it has been difficult to expand distribution in the market.
The present invention has been made in view of the above circumstances, and has been made light in weight and excellent in handleability by simplifying the structure, facilitating assembly, and reducing the cost. An object of the present invention is to provide a table-top stand device that can cope with the expansion of the distribution.

In order to achieve the above object, the present invention has taken the following measures.
That is, the desktop stand device according to the present invention includes a pedestal having a column hole opened on the upper surface, a support column erected by fitting a base end portion into the column hole of the pedestal, A support member provided with a connecting projection to be inserted into the tip end portion of the support column. The support column includes a skin tube formed of a flexible tube and a tip portion of the shell tube. A core formed by a metal wire inserted into the outer cylinder in a state in which a fitting hole for inserting the connection projection of the support is secured, and the core has a tip of the outer cylinder An inner surface abutting portion that is capable of abutting on the inner surface of the tube hole is provided near the portion.

In addition, it is preferable that the inner surface abutting portion of the core member is formed to have a size that expands the inner diameter by pushing the inner surface of the outer cylinder to the outside.
With such a configuration, the support column that supports the support such as the magnifying glass and the lighting fixture can be made to have a very simple structure, and the assembly can be facilitated and the cost can be reduced. Therefore, it is lightweight and has excellent handleability, and can cope with the expansion of distribution in the market.
It is preferable that the core material has a parallel structure in which two metal wires are snuggled by folding a metal wire longer than the outer cylinder into a folded state.

If it does in this way, the U-turn part which arises by the return | turnback of a metal wire can be used effectively, and the inner surface contact part as a core material can be formed, and formation of this inner surface contact part becomes easy.
In addition, when the support pillar is bent, the core material having such a structure causes a phenomenon in which the portions where the metal wires are snuggled are shifted in the longitudinal direction. At this time, the metal wires may be connected with each other or between the individual metal wires and the inner surface of the outer casing. High friction is generated between them and the bent state as the core material can be more strongly maintained by these high frictions. That is, it is advantageous in that the action of maintaining the bending state as the support pillar (the action of adjusting and setting the holding height, orientation, angle, etc. of the supported body can be stably obtained).

It is preferable that the inner surface abutting portion of the core material is formed as an outwardly bulged round by folding the metal wire.
In this way, when the metal wire is bent so as to be folded back, not only simply making a U-turn, but also generating an outward bulge, the formed inner surface abutting portion further increases the inner surface of the outer cylindrical tube hole. The action of pressing becomes stronger.
Therefore, as a reaction of the outer cylinder being pushed by the inner surface contact portion of the core material, the tip portion (a fitting hole as a support column and a portion into which the connection projection of the supported body is inserted) is deflated. (To reduce the diameter). Along with this, the connecting action when the connecting projection of the supported body is inserted into the tip end portion (fitting hole) of the support column becomes even stronger, which is preferable.

The core material is inserted into the outer tube so as to reach the base end portion of the support column inserted into the column hole of the pedestal, and when the base end portion of the support column is inserted into the column hole of the pedestal It is preferable that the width between the parallel states of the metal wire forming the core material is equal to or greater than the inner diameter of the outer cylinder.
If it does in this way, the effect | action which the longitudinal direction side surface of the both outer sides in a metal wire contact | abuts to the cylinder hole inner surface of an outer shell can be ensured (the effect which prevents that an outer shell is crushed is acquired). Therefore, when the base end portion of the support column is inserted into the column hole of the pedestal, a firm fixing force can be obtained without using fixing means such as an adhesive.

  The desktop stand device according to the present invention is simplified in structure, easy to assemble, and low in cost, and is lightweight and excellent in handling, so it can be used in the market. It can be done.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 4 show a first embodiment of a desktop stand device 1 according to the present invention. As shown in FIGS. 1 and 2, the table-type stand device 1 includes a pedestal 2, a support column 3, and a supported body 4, and the support column 3 is flexible and bent. It has a shape-retaining property that can maintain its shape. In the present embodiment, a magnifying glass is illustrated as the support 4.
The pedestal 2 is provided with a column hole 6 that opens on its upper surface. By inserting the base end portion 3 b of the support column 3 into the column hole 6, the support column 3 is erected and held on the pedestal 2. It is like that. Further, the support 4 is provided with a connecting projection 7 projecting from the outer periphery thereof, and a fitting hole 8 for fitting the connecting projection 7 is formed at the tip 3 a of the support column 3. In addition, the support 4 is connected to and held by the support column 3 by inserting the connection protrusion 7 of the support 4 into the fitting hole 8 of the support column 3.

The erection of the support column 3 with respect to the pedestal 2 and the connection of the supported body 4 with respect to the support column 3 do not employ fixing means such as an adhesive or screws, but are based on a fitting structure. Therefore, the table-top stand device 1 as a whole can be assembled very easily and quickly, and in some cases, rearrangement after assembly (disassembly, parts replacement, etc.) is also possible. Each part will be described in detail below.
The pedestal 2 does not fall even when the support column 3 is bent so that the supported body 4 is directed sideways, and further, even if a slight vibration is applied in this state, the base 2 does not rattle. The bottom area, bottom shape, self-load, etc. are determined.

Since conditions such as the size and weight of the supported body 4 and the length of the support column 3 can be changed in various ways, specific details cannot be specified unconditionally. However, it is necessary not to be so heavy that it adversely affects the handling as the table-top stand device 1, and it is necessary not to make it so large that it is inconvenient to store and carry.
The material of the pedestal 2 is not particularly limited as appropriate, for example, plastic, wood, metal, etc. However, if handling, storage, portability, and cost are taken into consideration, the base 2 is made of plastic. Is preferred.

In the present embodiment, a magnifier of the supported body 4 having a diameter of about 20 to 30 mm is applied. Moreover, the support pillar 3 shall select the length which protrudes from the base 2 in the range of 140-160 mm. In such a case, the pedestal 2 is preferably formed by a plastic plate having a side of 50 to 100 mm or a circle having the same size and a thickness of 10 to 15 mm.
In the column hole 6 provided in the upper surface of the pedestal 2 (the portion where the base end portion 3b of the support column 3 is fitted), the arrangement within the pedestal upper surface can provide the mounting stability as described above. For example, there is no particular limitation.

Therefore, for example, it may be the center of the upper surface of the pedestal 2, or may be a peripheral portion or a corner portion. However, in order to prevent the usage direction of the pedestal 2 from being restricted, it is preferable to arrange the pedestal 2 at the center of the pedestal 2.
It is not limited at all whether the column hole 6 penetrates the pedestal 2 up or down. However, if the column hole 6 is formed by post-processing, it is easy to process. Will be good.
The support column 3 includes an outer cylinder 10 formed of a flexible tube, and a core member 11 formed of a metal wire inserted into the outer cylinder 10.

The flexible tube forming the outer cylinder 10 needs to have a certain degree of hardness as having flexibility, and for example, a urethane hose that is commercially available as an air hose or the like should be used. Can do.
The core material 11 is inserted into the outer casing 10 so as to reach the base end portion 3b (the portion inserted into the column hole 6 of the base 2) as the support column 3. Further, the core material 11 has a predetermined length in the outer shell 10 so that a fitting hole 8 (a space for inserting the connection projection 7 of the supported body 4) can be secured in the distal end portion 3a as the support column 3. Has been inserted. And the inner surface contact part 13 is provided with respect to the front-end | tip part (location which faces the fitting hole 8) of this core material 11. FIG.

The core material 11 is formed so as to form a parallel structure in which two metal wires are snuggled by folding back a metal wire longer than the outer casing 10 in a folded state. As the metal wire material, a material having flexibility and shape retention enough to maintain a bent state, such as iron, copper, aluminum, brass, and stainless steel, is used.
In the present embodiment, a metal wire (iron wire) coated with vinyl is used to increase the durability of the metal wire, and to further improve the shape-retaining property against bending (reverse suppression effect). It is.

The metal wire is inserted into the outer shell 10 such that the folded portion is directed to the distal end side of the outer shell 10. And the above-mentioned inner surface contact part 13 is formed by this folding | turning part.
In the present embodiment, the folded portion (U-turn portion) of the metal wire is further rounded so that the folded portion, that is, the inner surface abutting portion 13 bulges wide (substantially circular). The ring shape of the
In the inner surface abutting portion 13, the outer diameter of the outer bulge radius (ring outer diameter) is larger than the inner diameter D of the outer cylinder 10, and the inner surface abutting portion 13 is inserted into the outer cylinder 10. When doing so, the tube hole of the outer cylinder 10 is forcibly fitted while slightly expanding the diameter.

Therefore, as shown in FIG. 3, the inner surface of the outer cylinder 10 near the distal end thereof comes into contact with the inner surface abutting portion 13 of the core member 11 and is further pushed outward. Then, in response to this pushing and spreading action, the outer cylinder 10 has an action such that the inner diameter of the portion (the portion in which the fitting hole 8 is formed as the support column 3) that is on the tip side of the inner surface abutting portion 13 is narrowed. (Figure 3 is exaggerated to some extent to facilitate understanding of these effects).
By such a narrowing action, the fitting hole 8 formed in the tip portion of the support column 3 becomes a tapered hole, and the inner diameter M (that is, M ≦ D) that is the smallest diameter is supported. The diameter is slightly smaller than the outer diameter T of the connecting projection 7 provided on the body 4 (M <T). Therefore, when the connection protrusion 7 is inserted into the fitting hole 8, the connection protrusion 7 can be firmly held. This is the connection between the support column 3 and the supported body 4. This is why a fixing means such as an adhesive or a screw is not required.

The diameter d of the metal wire forming the core member 11 is set to be less than half of the inner diameter D of the outer cylinder 10. That is, the width (2d + α: where α is a gap between the metal wires and includes α = 0) between the two metal wires in parallel is equal to the inner diameter D of the outer tube 10. It is as follows (2d + α ≦ D).
Therefore, when the core material 11 is inserted into the outer cylinder 10, the two outer side surfaces (except the inner surface abutting portion 13) of the two metal wires are in contact with the inner surface of the cylindrical hole of the outer cylinder 10. Even if they do not contact or come into contact with each other, the contact will be light, so that it is easy to insert most of the core material 11 into the tube hole of the outer tube 10.

On the other hand, as shown in FIG. 2, the column hole 6 of the pedestal 2 is formed so that the inner diameter H thereof is equal to or slightly smaller than the outer diameter S of the outer casing 10 (S ≧ H). . Accordingly, when the base end portion 3b of the support column 3 is inserted into the column hole 6, the outer peripheral surface of the outer cylinder 10 is in contact with the inner peripheral surface of the column hole 6 over the entire circumference. However, the diameter is narrowed down and the diameter is reduced.
At this time, as shown in FIG. 4, in a state where the base end portion 3 b of the support column 3 is inserted into the column hole 6, the outer cylinder 10 of the support column 3 can be tightened inward on the entire outer periphery. Thus, the outer cylinder 10 is elastically deformed to an inner diameter h in which the inner diameter D of the cylinder hole is reduced more than that (D> h). The reduced inner diameter h is set to be equal to or less than the width (2d + α) between the two parallel outer sides of the two metal wires forming the core member 11.

In other words, since h ≦ (2d + α), the two longitudinal side surfaces of the two metal wires come into contact with the inner surface of the cylindrical hole of the outer cylinder 10 as a result, and as a result, the base 2 The outer diameter S of the base end portion 3b of the support column 3 is retained (backed up) to be equal to or greater than the inner diameter H of the column hole 6 formed in the above.
In other words, since the base end portion 3b of the support column 3 is not crushed, a firm fixing force can be obtained. This is because an adhesive, a screw, etc. This is why no fixing means is required.

As long as the connecting projection 7 provided on the supported body 4 can be inserted into the fitting hole 8 provided on the tip 3a of the support column 3, its shape, outer diameter, protrusion length, etc. It is not limited. For example, it may be formed into a round bar shape, a square bar shape, or a spherical shape.
The outer diameter T of the connecting protrusion 7 is preferably equal to or greater than the inner diameter D of the outer cylinder 10 (T ≧ D). However, as described above, the inner surface abutting portion 13 of the core 11 is used. Depending on the strength of the action of squeezing the tip of the outer shell 10, the outer diameter T of the connecting projection 7 may be made smaller than the inner diameter D of the outer shell 10 (T <D). is there.

As is apparent from the above description, in the desktop stand device 1 according to the present invention, the support column 3 that supports the supported body 4 such as a magnifying glass can have a very simple structure, which facilitates assembly and is lightweight. Can be made. Therefore, it is excellent in handleability and can be reduced in cost.
By the way, the assembly procedure of the tabletop stand device 1 will be described. The core 11 is inserted into the outer casing 10 to complete the assembly of the support column 3, and the base end 3 b of the support column 3 is attached to the base 2. The connecting projection 7 of the supported body 4 is inserted into the tip 3 a (fitting hole 8) of the supporting column 3. With this alone, the desktop stand device 1 can be completed.

Moreover, since the support pillar 3 comprises the core 11 made of a metal wire, the support pillar 3 can be bent at an arbitrary angle in an arbitrary direction at an arbitrary angle, and can maintain a bent state. It is. The base end portion 3b of the support column 3 is rotated in the column hole 6 of the pedestal 2, or the connection projection 7 of the supported body 4 is rotated in the distal end portion 3a (fitting hole 8) of the support column 3. It is also possible.
For this reason, it is very easy to apply a magnifying glass to the place you want to see when performing fine work such as assembling and adjusting the sewing machine, and fixing threading and thread jamming during sewing. And it can be done reliably.

When the metal wire is folded and used as the core material 11 of the support pillar 3, the portion where the metal wire is snuggled shifts in the longitudinal direction, and high friction occurs between the metal wires, and this high friction As a result, the core material 11 can maintain the bent state.
Compared to the case where the core material 11 is formed of a single thick metal wire, this action is not only more effective in maintaining the bent state, but also has the advantage that it is easy to bend. The advantage of being easy to insert is obtained, which is preferable.
[Others]
The present invention is not limited to the above-described embodiment, and can be appropriately changed according to the embodiment.

For example, the pedestal 2 may have an oval shape, a rectangular shape, another polygonal shape, or a three-dimensional shape such as a hemispherical shape. When the pedestal 2 is hemispherical or the like, the upper surface thereof can be defined as a range (a surface facing upward) where the pedestal 2 can be seen in plan view. Therefore, the arrangement of the column holes 6 (position where the support column 3 is erected) can be arbitrarily set within the range defined as the upper surface.
The column hole 6 is not limited to be formed in the vertical (vertical) direction, and may be inclined obliquely.

In the core material 11 of the support pillar 3, the shape of the metal wire folded back is such that the U-turn projecting portion 20 is further forward than the inner surface contact portion 13 as shown in FIG. 5 in the second embodiment of the core material 11. The shape may be formed (in short, the inner surface contact portion 13 is not formed using the folded portion but is formed near the folded portion).
As shown in FIG. 6 in the third embodiment of the core material 11, the folded portion of the metal wire (the rounded portion of the outer bulge) is formed in an elliptical ring shape. It is also possible to make it. In addition, as shown in FIG. 7 in the fourth embodiment of the core material 11, the folded portion (the rounded portion of the outer bulge) of the metal wire material may be formed in an asymmetric shape. In short, the shape of the portion where the metal wire is folded back and the rounded portion shape of the outer bulge as the inner surface contact portion 13 are not limited at all.

In the core material 11 of the support pillar 3, the metal wire material can be formed by a single metal wire material (thick material) that can be inserted into the tube hole of the outer shell tube 10 in addition to the parallel structure by folding back. is there. In this case, the inner surface contact portion 13 can be formed into a bulging shape by bending the core material 11 (metal wire) flatly or by forming it into a spherical shape by partial melting, in addition to being formed by bending. is there.
The support 4 is not limited to a magnifying glass as described above. For example, as shown in FIG. 8, it is possible to use a supported body 4 having a small luminaire 22 using an LED or a filament sphere and a holder 21 for holding the luminaire. The connection projection 7 is provided on the holder 21.

In the example shown in FIG. 8, the holder fixture 21 is clamped so that the lighting fixture 22 can be freely attached and detached. However, the holder fixture 21 and the lighting fixture 22 are fixed by bonding or screwing. The structure may be used, or the holder device 21 and the lighting fixture 22 may be formed as a single unit from the beginning (meaning that the holder fixture 21 is omitted and the connecting projection 7 is provided on the lighting fixture 22).
In addition, the supported body 4 can be arbitrarily selected as an object to be held, for example, as a clip such as a clothespin.

  The use of the desktop stand device 1 according to the present invention is not limited.
